“…Meanwhile, the XRD patterns of CaO samples showed peaks at 2θ (º) of 32.21; 37.38; 53.87; 64.15; and 67.37, which are characteristic of crystalline peaks of CaO from thermal decomposition of calcium acetate. The XRD pattern of CaO was similar to the results reported [13]. The peaks of the XRD patterns of mesoporous ZSM-5 and CaO samples were appeared on all CaO/H-ZSM-5 samples, indicated that the samples contains CaO crystals and ZSM-5.…”

Transesterification of used cooking oil was carried out over calcium oxide supported on mesoporous H-ZSM-5 prepared from kaolin as solid base catalysts. Solid basic catalysts investigated in this study were characterized by XRD, FTIR spectroscopy, and N2 adsorption-desorption techniques. The XRD pattern showed peaks corresponding to the CaO and mesoporous ZSM-5 in the sample. The peak intensity of the CaO increased as the CaO loading in ZSM-5 was increased. The characterization based on FTIR spectroscopy revealed that CaO/H-ZSM-5 solids have functional groups characteristics of both CaO and mesoporous H-ZSM-5 which appeared in the band at around 550 cm -1 and 480 cm -1 . The isotherm of N2 adsorption-desorption of CaO/H-ZSM-5 indicated the type IV isotherm with the presence of hysteresis loop. For the catalytic activity, the biodiesel yield using catalyst of 10 % CaO/HZSM-5 (100 %), 30 % CaO/HZSM-5 (100 %), 50 % CaO/HZSM-5 (100 %) were 24.34, 27.37, and 29.73 %, respectively. It also related with the basic active site, when loading CaO increased, the basic active site also increased.

“…The NaOH catalyst represented the esterification using homogenous base catalyst CaCO 3 , A. granosa, and P. undulata after the third cycles. The results indicated a slight catalyst deactivation because of the leaching of the CaO active species into the reaction medium [27]. The decrease in CaO contents are shown in Table 5.…”

The aim of this study was to develop fly ash-supported CaO catalyst derived from waste mollusk shell of Anadara granosa and Paphia undulata for transesterification of palm oil to yield biodiesel. The active precursor Ca(OH) 2 of the catalyst has been developed from calcination of waste mollusk shell, while the mesoporous has been prepared using the wet impregnation method. The results demonstrated that the mollusk shell-derived catalyst could gain the yield of biodiesel of 92 and 94 % for A. granosa shell and P. undulata shell, respectively. The obtained yield was comparable with the yield of biodiesel gained from CaO catalyst derived from reagent grade CaCO 3 (yield = 94 %). The optimum condition was achieved at catalyst loading of 6 %, reaction temperature of 60°C and reaction time of 2 h. The reusability study showed that the developed catalysts exhibited higher recycle degree characteristic indicated by 50 % yield reduction after three reuse cycles.

“…Glycerol on the surface of catalysts may cause catalysts loss activity. CaO has higher trasnesterification activity among all Alkali and alkaline earth oxides, it would react with glycerol produced from transesterification process to form Ca-glyceroxides [20]. It might be resulted from the poison process by Ca-glyceroxides is decrease reutilization.…”
